We sent out our first paper on food sharing for peer-review. Fingers crossed. In the study, we revisit the original findings on reciprocal food sharing in vampire bats and address 4 alternative evolutionary explanations of food sharing in light of new data from 53 nights over 2 years when we induced food sharing in a colony of 25 vampire bats of mixed relatedness and equal familiarity (more info here). This colony is cared for by the Organization for Bat Conservation.
If you would like to get a copy of the draft manuscript, just send me an email, especially if you would like to give comments, suggested, or criticisms.
